The lowersectionv may -be providedfwith push elements shown' herein as` plu s'.

The upper section.'` may'- have recesses 27 therein to accommodate the plug feet 2,5 and prevent interference therefrom'with the, rotative adjustmentof .the ends of the sections toward n .ither- The construction is 4such that when one of the plugs 2 3 is adjusted down and the other is ac ljus'ted 'u pV Ithe lower section will b e given'la', 'aitivarota'tive adjustment- Tvadiust adseafie. theplugSZ in p0# sition, s crevi7` plugs 29 may threaded in the hQlfS recelyingthe agustin" plugsnand bearag'ainst then per e y s of t elatter.

To remove the parts, tie pull and push plugs are loosened and the sections may then be withdrawn axially from the housin bore.

-The pull lugs, may a slabbed off at 45 (Fi s; 2 anll)3) andthe push plugs may be slab ed ofi at 47' (Figs.v 2 and 4) to permit thev sections to be sli-d to 4and from thebore without interference therefrom.

When the sections'4 are-originally assembled, .they may be adjusted so that their thicker ends are closely adjacentl 'as shown in Fi 3, but after they become Worny from the friction o f the spindle thereomtheir narrower ends may be adjustedtoward one another from time to time, until finally they are closely adjacent as shown in- Fi 4. This range of ad`ustment will serve t r life of the parts. lfhen the worn sections may be removed and new ones substituted therefor.
